Bishop Ricken also approved the chapel as a diocesan shrine, recognizing its long history as a place of pilgrimage and prayer.

In early October 1859, Adele reported seeing a woman clothed in white and standing between two trees, a hemlock and a maple.

Adele described the woman as surrounded by a bright light, clothed in dazzling white with a yellow sash around her waist and a crown of stars above her flowing blond locks.

Other women joined her in her work and they formed a community of sisters according to the rule of the Third Order Franciscans, although Brise never took public vows as a nun.

[9] This chapel bore the inscription "Notre Dame de bon Secours, priez pour nous" [Our Lady of Good Help, pray for us], giving the shrine its original name.

The night of October 8, 1871, a firestorm began near Peshtigo, Wisconsin, that spread through the woods and towns, consuming everything in its path.

Some people assume that, driven by strong winds, the conflagration leaped across Green Bay of Lake Michigan and began burning huge sections of the Door Peninsula.

When the firestorm – whatever its origin – threatened the chapel, Adele Brise refused to leave and instead organized a procession to petition the Virgin Mary for her protection.

The largest annual gathering at the chapel happens on the feast of the Assumption of the Blessed Virgin Mary, on August 15, celebrated with an outdoor Mass and a procession around the grounds of the shrine.
